When power and ground are supplied, the power window relay continues to be energized, and the power win-
dow can be operated.
The retained power operation is canceled when the driver or passenger side door is opened.
INTERRUPTION DETECTION FUNCTIONNBEL0102S05Front power window main switch and front power window switch RH monitor the power window regulator motor
operation and the power window position (full closed or other) for driver's and passenger's power window by
the signals from encoder and limit switch in front power window regulator LH or RH.
When front power window main switch or front power window switch RH detects interruption during the fol-
lowing close operation in the driver's or front passenger's side door,
Iautomatic close operation when ignition switch is in the ªONº position
Iautomatic close operation during retained power operation
